John Lennon and Yoko Ono were a legendary artistic couple who, even after the breakup of The Beatles, continued to have a profound influence through their music, avant-garde art, and global peace movements, all based on the theme of "love and peace." After meeting in 1966 and marrying in 1969, they collaborated on groundbreaking works, with John producing classic songs such as "Imagine," and Yoko becoming a pioneer of contemporary art, continuing their work even after John's death.
